    Opening ALAN 42 frequency ranges

    Hi, I purchased Alan 42 Multi from Poland and upon pressing SC and LCR together while turning on the radio, there's no option to select band plan. All elements on the LED just turn on and after a few seconds it goes into regular channel display. No option to select I, I2, D, .... So I played...

    Ranger RCI-2950DX power consumption

    I take it as a universal boat anchor. ANL is not used in the Woods, usually, but it comes in handy in urban environment. I'm thinking more towards uBitX after few iterations, after they manage to smooth out the edges, and include AGC, fix RX/TX audio and make it 10W across the whole band. Then...

    Ranger RCI-2950DX power consumption

    I'm using home brewed pack of 9 NCR18650s, balanced and IR-matched, each 3400mAh, so a total of around 100 Watt-hours (3s3p configuration). This suffice for 1.5-2 hours of TX on FM/AM. Total weight of such package is 2.5kg, including the RCI, which is not bad. But the problem starts when I want...

    Ranger RCI-2950DX power consumption

At 100W PA, that'd be no discussion, but 8-10W FM shouldn't need such power. Specs for FT-817 sensitivity-wise on...

    Ranger RCI-2950DX power consumption

    Yes, it's sort of typical that used RCIs have been improperly modded by the previous owner, but this is not the case. My warranty seal is still unbroken, no-one was inside yet. On SSB, the current draw is around 0.6A with no modulation, only on FM/AM it rises to 4.8A - 6A depending on the...

    Ranger RCI-2950DX power consumption

    Hey there, 2950DX is one of my most favoured 12-10m radios so far, but I can't get over some of its quirks. One of the major ones is its power consumption. For 10W on FM (max), it's pulling whopping 6A from 12V supply. While on grid, this may not be an issue, other than handling the extra heat...
